Crafted in 18k Yellow Gold, our Heavy Mixed Belcher Extension Chain measures 18". One of our most classic links, in a timeless repeating pattern. This "mixed" chain features one half with a heavy gauge and the other with a medium gauge. Medallions can be worn on both the center ring and the end of the extension link. Choose a medallion for the base and then use a connector to add additional medallions to the center to create a cascading look. You can also slide Heart Beats right onto the chain.
